Yesterday Steve and I fought this Black Powder scenario out of the Rebellion supplement.
Its a tricky one because to reflect the problems of heavy fog causing disruption on the day, units can only pass their command roll on a 7 or less and a blunder occurs on the roll of an 11 or 12.
For the British, their command rolls go up to 9 when Cornwallis arrives with reinforcements but this can only happen after the British have started losing units and Cornwallis has to dice on or below the number of beaten British units using one D6.
Grant's big American brigade has now broken and with that, any chance of Washington winning at Germantown.
Cornwallis has just arrived too and his lead battalion has shown on the right flank but the day is won.
A pretty big AWI battle this with 16 American battalions with 2 cavalry regiments up against 11 British battalions (12 if we include the late arriving one from Cornwallis).
The chaos caused by the fog made it frustrating for both sides too with blunders and failed command rolls happening all the way through the game - a novel twist to Black Powder.
